Chapter 10, Problem 10.29P

Interpretation Introduction

Interpretation:

The fraction of $\text{ethane-1,2-dithiol}$ at the given $\text{pH}$ conditions has to be calculated.

Concept introduction:

The fraction of $\text{ethane-1,2-dithiol}$ can be calculated as,

${\text{α}}_{{\text{H}}_{\text{2}}\text{A}}\text{=}\frac{{\left[{\text{H}}^{\text{+}}\right]}^{\text{2}}}{{\left[{\text{H}}^{\text{+}}\right]}^{\text{2}}\text{+}\left[{\text{H}}^{\text{+}}\right]{\text{K}}_{\text{1}}{\text{+K}}_{\text{1}}{\text{K}}_{\text{2}}}$

With the above equation, the fraction of $\text{ethane-1,2-dithiol}$ at the given $\text{pH}$ conditions can be measured.
